Interrupts not waking FreeRTOS up in Tickless mode

[dfer]

Hi

I'm working with FreeRTOS with Tickless (RTC) and I was wondering what one should do in order to avoid the FreeRTOS Idle Task to be waken up every time an Interrupt Service Routine has completed the execution.

In Cortex-M4 the SLEEPONEXIT flag in SCR should help with this feature but I cannot let it work with Nordic. Any hints?

Thanks in Advance.
